Road to improving k-space trajectory for free-running self-gated 5D cardiac MRI at 0.55 Tesla
Impact: By enabling the exploration and
optimization of k-space trajectories for free-running cardiac MRI at 0.55 T,
this work will unlock its full potential of sharpness, contrast, and spatial

Enabling Lower Dose Contrast Enhanced Cardiac Magnetic Resonance Imaging at Mid-Field (0.55T) with Gadopiclenol
Impact: Cardiac MRI for chronic ischemic heart failure is achievable with lower doses
of gadolinium contrast agent via injection of gadopiclenol, while maintaining
excellent image quality and infarct detection on a mid-field scanner.

Characterisation of glioblastoma enhancement and tissue relaxometry at 0.55T: a comparison with 3T
Impact: 0.55T MRI assessment of glioblastoma T1 enhancement was comparable to 3T. This supports more accessible tumour imaging and intraoperative use. Combined with the measured T2 and T2* values, this data can inform mid-field brain sequence optimisation and accurate tumour characterisation.

Tapping into the potential of 0.6T MRI for non-contrast brain perfusion imaging: pCASL and VSI finger tapping and multi-delay
Impact: Non-contrast-enhanced
brain perfusion measurements are feasible at midfield (0.6T) using the recommended
(multi- and single-delay) pseudo-continuous arterial spin labeling (ASL) or velocity-selective‑inversion
(VSI) ASL. This could potentially increase access to perfusion imaging outside of
academic hospitals.

Gravitational Dependence of Lung Oxygen-Enhanced ΔR2* with Upright 0.5T MR
Impact: Low-field
open MRI captures posture-dependent lung oxygenation, revealing gravitational
effects not measurable with conventional supine MRI. This enables new
